blkarray -- extensions and modifications of tabular support
This package is even less supported than any of David Carlisle's other
packages. It was written a long time ago, and is still documented using
the conventions of LaTeX2.09 (although it appears to work with current
LaTeX releases).
In 2014 it had a minor update to work with LaTeX2e font initialisation
and in 2015 a second update to avoid a clash with amsmath's use of box0.
Apart from these couple of lines all the code dates back to 1992 and
was more of a thought experiment than production code.
However people seem to find uses for it.
It is not really a package for using in documents in
its present state, but if you are interested in coding tables of
various sorts in TeX, you may be interested to experiment with it...

blka­r­ray – Ex­tended ar­ray and tab­u­lar

An ex­per­i­men­tal pack­age which im­ple­ments an en­vi­ron­ment,
blockar­ray, that may be used in the same way as the ar­ray or
tab­u­lar en­vi­ron­ments of stan­dard LaTeX, or their ex­tended
ver­sions de­fined in ar­ray. If used in
math-mode, blockar­ray acts like ar­ray, oth­er­wise it acts like
tab­u­lar.

The pack­age im­ple­ments a new method of defin­ing col­umn types, and
also block and block* en­vi­ron­ments, for
spec­i­fy­ing sub-ar­rays of the main ar­ray. What’s more, the
\foot­note com­mand works in­side a blockar­ray.
